Composite slab bridges are being increasingly employed because of their many design advantages. In standard composite slab bridges, a bearing is generally allocated under each main girder. However, if the composite slab bridge has long span or continuous girder, the configuration near support may become complex due to the large size of bearing. Because of those factors, in this study, a series of 3D finite element analysis is carried out in order to propose the configuration which can reduce the number of bearings.
